step

Deinterleave input symbols using a set of shift registers
with specified delays

Syntax

Y = step(H,X)

Description

Y = step(H,X) restores the original ordering
of the sequence, X, that was interleaved using
a multiplexed interleaver and returns Y. The input X must
be a column vector. The data type for X can be
numeric, logical, or fixed-point (fi objects). Y has
the same data type as X. The multiplexed deinterleaver
object uses N shift registers, where N is the number of elements in
the vector specified by the Delay property. When
a new input symbol enters the deinterleaver, a commutator switches
to a new register. The new symbol shifts in while the oldest symbol
in that register is shifted out. When the commutator reaches the Nth
register, upon the next new input, it returns to the first register.
The multiplexed deinterleaver associated with a multiplexed interleaver
has the same number of registers as the interleaver. The delay in
a particular deinterleaver register depends on the largest interleaver
delay minus the interleaver delay for the given register.

Note:H specifies the System object™ on which
to run this step method.

The object performs an initialization the first time the step method
is executed. This initialization locks nontunable
properties and input specifications, such as dimensions,
complexity, and data type of the input data. If you change a nontunable
property or an input specification, the System object issues an
error. To change nontunable properties or inputs, you must first call
the release method to unlock the object.
